i want to change the composition of the outlet flows for a three phase separator in aspen hysys in order to design the separator and get the real composition in the field, any idea ?

sorry, there is a fallacy in your question, you are in the design stage but you want get the real composition in the field. How could it be?

logically, to get actual outlet composition (in the field) you have to get your 3-phase separator installed and before that you need to design it.

Better to describe it clearly so that you could receive good feedback.

Thx.-PN
